I'm not sure what you mean by "can I install grub on boot drive?"; I have never seen such a prompt. What I see is after choosing to partition manually ( "something else" ), on the partitioning screen you can choose where to install grub to. One of the automatic choices however, just installs it to /dev/sda without asking, and that is intentional.
